To fetch an element of an Array you can just specify the position of the element in your query.
Say if you have a table like
'test_table' with a field 'arr_clmn Array<STRING>', you can get the first element of the array as
SELECT arr_clmn FROM test_table;
Or if you are looking at exploding the row itself to multiple rows you can do so with
SELECT * FROM test_table LATERAL VIEW explode(arr_clmn) exp_arr AS arr_elmnt;
